On arrival in Enniskillen, they were welcomed by the Lord Lieutenant of County Fermanagh, Viscount Brookeborough, and First Minster Arlene Foster, who said she was thrilled to see the couple in her constituency.

"I am delighted to welcome the Duke and Duchess of Gloucester to Northern Ireland and particularly to Fermanagh and south Tyrone," she added.

"I am extremely proud of this beautiful part of Northern Ireland, and I look forward to showcasing this area at its very best.

"The duke and duchess will have the opportunity to sample the beauty of the local landscape and meet people from different sectors of the local community."

The visit by the Duke of Gloucester, who is the Queen's cousin and often represents her at events around the world, was also praised by the Secretary of State for Northern Ireland, James Brokenshire.

"I can assure the royal couple of a very warm welcome,"Mr Brokenshire said.

"Visits by the Royal Family to Northern Ireland are always very welcome, and I am particularly pleased that the Duke and the Duchess of Gloucester are visiting today. Their visit is an opportunity for us all to pay tribute to the hard work and outstanding contribution of Northern Ireland's businesses, charities and local institutions."

The royal couple will join thousands of people later today at the 98th Clogher Valley Show. Among the highlights at the agricultural event will be the Twelve Championships, in which exhibitors from all over the island of Ireland will present their prized livestock.

The show is an important annual date in the country's agricultural calendar.
